Phenol is a highly toxic compound and widely produced from various industrial wastes.
Removal of phenol by chicken bone ash (CBA) from an aqueous solution was studied. CBA
was prepared and characterized by scanning electron microscope (SEM) and X-ray
diffraction (XRD). The SEM analysis shows that the CBA has a rough and large porous
surface with interconnected irregular shape cavities. The XRD proved that hydroxyapatite
was the main component of the ash. Batch and column adsorption procedures were …
